JOURNAL-BEARING.

SPECIFICATION forming part of Letters Patent No. 723,839, dated March 31, 1903. Application filed February 3, 1903. Serial No. 141,684. (No model.)

To aZZ whom it may concern:

Be it known that I, EDWARD J. DECKER, of the city and county of Philadelphia, State of 'Pennsylvania, have invented an Improvement in Journal-Bearings, of which the following is a specification.

More particularly my invention relates to. that class of journal bearings known as filled bearings, in which the bearing-face is provided with a series of grooves or pockets containing graphite or other com minuted an- In such bearings the strength of the casting is more or less weakened by the pockets or grooves, especially where they are made large enough to contain a material quantity of graphite, and theyare consequently liable to crack when subjected to heavy pressure or blows.

It is one of the objects of-niy invention to brace or strengthen the casting to resist this tendency to crack, while permitting large pockets to be employed and enabling the pocket-walls to be made less heavy, it 'desired.

It is also an object of my invention to enable the filling material to be held more firmly in the pockets, and, further, to avoid the formation of sharp angles or corners in the pockets.

In carrying out my invention I form the inner curved or bearing face of the casting of a series of transverse ribs, forming between one another and between the outer ribs and the end walls a series of pockets for the filling material, and I connect some or all of these transverse ribs by longitudinal braceribs,which serve the dual function of strengthening the casting and of dividing the pockets.

into smaller sections for the filling material. In the drawings, Figure 1 is a perspective View of the casting or shell of a journal-bearing embodying myinvention. Fig. 2 is a plan view of the same on a reduced scale; and Fig. 3 is plan view similar to Fig. 2, illustrating a diiferent form.

The shell a is a single casting, usually of brass or bronze, having the customary external'form and the inner curved bearingface, which-fits the journal. The inside of the casting between the curvedend walls b b is hollow and is formed with a series'of integral curved ribs 0 c, which form a series of pockets d, adapted to be filled with graphite ries and the.end walls b b. As shown, these outer transverse ribs c 0 do not extend entirely across the face of the casting, but terminate at or near the median line. This is not, however, essential to my invention, and the ribs 0 0' may, if desired, be extended entirely across the casting from one side to the other.

e represents longitudinal brace-ribs connecting adjacent transverse ribs and dividing the pockets into smaller sections.

In the construction shown in Figs. 1 and 2 the end ribs 0 c terminate on the median line of the casting, and the ribs e are formed in a continuous ribextending on the median line from end wall to end wall and uniting not only the adjacent ribs 0 c and c 0, but also the outer ribs 0 and the end walls b.

In the construction shown in Fig. 3 the outer transverse ribs 0' c extend from opposite side walls of the casting to a distance beyond the median line, and two sets of longitudinal ribs 6 are employed, one extending continuous ribs e eon opposite sides of the median line brace the casting at the points where cracking is most liable to occur. They also divide the bearing-surface into a nnmber offsmall pockets.

It is not necessary to my invention,however, that the ribs e, whether one or more be used, shall extend from end wall to end wall or shall unite all of the adjacent ribs 0 e and c c, as

outer faces of which are curved to correspond with the curvature of the ribs 0 c and end walls I) I). These strips form ends for the pockets to retain the filling material in place.

The details of construction may be varied Without departing from my invention.

WVhat I claim as new, and desire to secure by Letters Patent, is as follows:

1. A journal-bearing having a curved inner face adapted to fit the journal and formed of a series of transverse ribs forming pockets to retain the filling material and longitudinal connecting-ribs between adjacent transverse ribs uniting said ribs together and dividing the pockets formed by them into sections.

2. A journal-bearing having acurved inner face adapted to fit the journal and formed of a series of transverse ribs forming pockets to retain the filling material, and a longitudinal rib extending from end wall to end Wall and uniting adjacent transverse ribs together and the outer transverse ribs to the end walls and dividing the pockets into sections.

3. A journal-bearinghavingacurved inner face adapted to fit the journal and formed of a series of transverse ribs forming pockets adapted to retain the filling material, the outer ribs of said series extending beyond the median line of the casting and a longitudinal rib out of the median line of the casting extending from end Wall to end wall and uniting adjacent transverse ribs together and the outer transverse ribs to the end walls.

4:. A journal-bearing having acurved inner surface adapted to fit the journal and formed of a series of transverse ribs forming pockets adapted to retain the filling material, the

outer ribs of said series extending from opposite side Walls beyond the median line of the casting, and two longitudinal ribs extending each through the end of one of said outer transverse ribs and uniting adjacent transverse ribs and dividing the pockets formed by them into sections.

5. A journal-bearing havinga curved inner face adapted to fit the journal and formed of a series of transverse ribs forming pockets adapted to retain the filling material, the outer ribs of said series extending from opposite side walls beyond the median line of the casting, andtwo longitudinal ribs extending each from end Wall to end Wall through the end of one of said outer transverse ribs and uniting adjacent'transverse ribs and dividing the pockets formed by them into sections.

6. A journal-bearing havinga curved inner face adapted to fit the journal and formed of a series of transverse ribs, the outer ribs of said series terminating part way across the face of the casting, and a longitudinal rib uniting said transverse ribs and dividing the pockets formed by them into sections.

7. A journal-bearing having its bearingface formed of transverse ribs forming pockets to retain the filling material with a longitudinal rib uniting adjacent transverse ribs and dividing the pocket formed thereby into sections.

In testimony of which invention I hereunto set my hand.
